Elmo is the codename of the Power Management IC (PMIC) of the PS Vita. The PMIC is responsible for generating the various voltages required by Kermit and probably other devices on the board.


The Elmo PMIC is manufactured by Fujitsu. All models are part of the custom "MB44" series but the exact model used depends on the unit.

Ernie can communicate with Elmo via I²C.
